Most of my opinions stated above are positive. That's because I'm honestly impressed with BlackBerry 10. I left the demo feeling optimistic for RIM's future. But it's my job to be realistic.

As impressive as the BlackBerry 10 software is, and regardless of how much I like the QWERTY device, RIM is facing an up-hill battle in reviving the BlackBerry brand.

The number one challenge for RIM: Apps. Regardless of whether or not the average smartphone user really needs even a fraction of the mobile apps available on RIM-rival platforms, including iOS and Android, the users think they need them. And in this case, perception has become the reality.

It's a fact that RIM has fallen behind its rivals when it comes to app quality and selection, and this is a huge reason why RIM decided to release a brand new OS instead of improving on its old foundation. The current BlackBerry OS is difficult for developers to work with, and BlackBerry 10 should be a lot simpler for developers.

RIM's future isn't just about the BlackBerry 10 hardware or software; it's about developer support--and not just independent developers but the big-name developers that have shunned BlackBerry in the past. The Netflixs. The Amazons. Dunkin' Donuts and Starbucks. Instagram.
